Best Plus-Size Diapers for Adults: Secure Protection & Reliable Fit

Incontinence doesn’t come in one shape, size, or solution. At NorthShore, we believe everyone deserves incontinence products that fit right and perform exceptionally — which is why we design solutions for all body types, including plus-size and bariatric sizes up to 3XL.

Whether you need reliable overnight protection that stops leaks in their tracks, prefer the flexibility of a pull-on for more active days, or want a discreet liner that fits inside your own underwear, NorthShore has you covered (literally) from XS to 3XL. Because wearing the right size isn’t a luxury, it’s the key to staying dry and in control.

Below, we’re spotlighting three top-rated incontinence solutions—a high-absorbency tab-style diaper, a body-hugging pull-on, and a powerful pad-style liner—each crafted with extended sizing and everyday wear in mind.

Not sure which size to choose? Sizing can vary between brands and even between different product types. That’s why we recommend measuring your waist and hips (rather than relying on clothing sizes) and using the detailed sizing charts listed for each product below to ensure the best possible fit.

Package of NorthShore MEGAMAX adult diaper with tabs, designed for unisex use and up to 12 hours of maximum absorbency

1. MegaMax® Overnight Diaper Style Briefs with Tabs

Now in 2XL & 3XL: Plus Size Protection with Mega Confidence

MegaMax is that brief. Built for up to 12 hours of dependable protection, this smooth, plastic-backed unisex adult diaper is a customer favorite for managing moderate-to-heavy incontinence, especially overnight.

We heard from people in the NorthShore community who shared the challenge of finding adult diapers that truly fit, stay in place, and prevent leaks without constant adjusting. So, we developed MegaMax 2XL and 3XL, designed to fit waist sizes from 60 to 96 inches and deliver the same reliable performance with added space to move confidently. The wide, non-stretch wings help keep the brief securely in place even on larger bodies, so say goodbye sagging and slipping.

Why You’ll Love It:

  • Sizes from X-Small to 3X-Large (ideal if you wear a 60-96 inch waist size)

  • Up to 12 hours of leak protection*

  • Non-stretch wings for a secure, stay-put fit

  • Super-wide absorbent core for full front-and-back coverage 

  • Tall stand-up leak guards, leg cuffs, and waistband elastics to keep everything in place (great for side sleepers)

  • Smooth waterproof backsheet resists odors and keeps skin dry

How to Measure for Adult Diapers

Finding the right fit is key to preventing leaks, ensuring comfort, and getting the most out of your brief, pull-up, or liner. Because sizing can vary by brand and product style, we recommend using body measurements rather than relying on clothing sizes. Using a tape measure, follow these simple steps to find the best size:

1.      Waist Measurement: Measure around the widest part of your waist or lower belly (often around or just below the belly button).

2.      Hip Measurement: With feet together, measure around the fullest part of your hips or buttocks.

3.      Compare both measurements and use the larger number to select your product size using the sizing charts provided.

Plus-Size Incontinence Products Should Fit Right, Not Frustrate

At NorthShore, we believe that plus-size incontinence products should do more than fit —they should empower. A great fit is about more than comfort; it’s about dignity, confidence, and the freedom to live without compromise. That’s why extended sizing is built into the design, not tacked on as an afterthought.

Whether it is a protective tab-style brief, snug pull-up, or discreet liner, every product is created to fit real bodies and support daily routines with confidence. Protection should feel like it was made to move with the body, not work against it.

For those exploring the best option or unsure about sizing, the NorthShore Sample Program makes it easy to test the right style and fit. Our Customer Care experts are also available to offer helpful, pressure-free guidance based on individual needs.
